Answer

The rectangular form is $\frac{\sqrt{2}}{2} - \frac{\sqrt{6}}{2} i$

Work Step by Step

$\sqrt{2}(cos(-60^\circ)$ + $isin(-60^\circ))$ = $\sqrt{2} \cdot \frac{1}{2}$ + $\sqrt{2} \cdot i \cdot (- \frac{\sqrt{3}}{2})$ = $\frac{\sqrt{2}}{2} - \frac{\sqrt{6}}{2} i$ The rectangular form is $\frac{\sqrt{2}}{2} - \frac{\sqrt{6}}{2} i$
